Calculate fugacicty of a certain subtance

[shanx]

Hi everybody,
i have to calculate fugacicty of a certain subtance.

i am given temerature and pressure of a that substance and its compressiblity for the vapor phase.

i am also given its vapor pressure at the same temp., its molar volume, and its isothermal compressibilty at the same temp and i am told it is independent of pressure.

can anyone tell me how to approach this problem.

regards,
shanx

first find the reduced temp and press that will tell you whether its high density or low density if its high your charts if its low use the virial equations at least start there if you still don't know just ask and i can work it out for you.
